Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Lipids, which can be found in oil based salad dressingsand ice cream, during digestion are splitted into
A
fatty acids and glycerol
B
glycerol and amino acids
C
glucose and fatty acids
D
glucose and amino acids
Explanation: 

Detailed explanation-1: -Solution. All lipid digestion takes place in the small intestine fatty acid and glycerol are the digestion products of lipids. Fatty acids and glycerol are incorporated into small spherical water soluble droplets micelles.

Detailed explanation-2: -As pancreatic lipase enters the small intestine, it breaks down the fats into free fatty acids and monoglycerides.

Detailed explanation-3: -lipase, any of a group of fat-splitting enzymes found in the blood, gastric juices, pancreatic secretions, intestinal juices, and adipose tissues. Lipases hydrolyze triglycerides (fats) into their component fatty acid and glycerol molecules.

Detailed explanation-4: -Phospholipids. The predominant PL in the lumen of the small intestine is PC, which is found in mixed micelles that also contain cholesterol and bile salts. The digestion of PLs is carried out primarily by pancreatic phospholipase A2 (pPLA2) and other lipases secreted by the pancreas in response to food intake.

Detailed explanation-5: -Lipids are digested mainly in the small intestine by bile salts through the process of emulsification, which allows lipases to divide lipids into fatty acids and monoglycerides.
